Review on Walker Universal CalCat Carb 80907 Catalytic Converter for Exhaust by Ronnie Cole
Surrender your runaways - remove the Magnaflow and deploy that Walker cat. PASS in double digits.
installed on my chevy k1500 93 years old. There were emissions dips with NOx exceeding 1800 ppm. It was loud 1200 or 1400 ppm. After installation, my Nox dropped to 2ppm and 15ppm in the Dino test. There was ZERO CO2 across the board and HC were in the 20's. This truck has struggled to get through the past 4 years. Replaced everything related to emissions before this 3-way cat was installed. TOP price and works. Thanks.
